Title: Fault diagnostic device for water temperature sensor
Inventor: TANIGUCHI SATORU
IPC: F02D45/00
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To accurately determine whether a fault occurs in a water temperature sensor for an internal combustion engine or not. SOLUTION: A control circuit 30 for an internal combustion engine receives the output of a water temperature sensor 10 and also engine-operational parameters which affect the rising speed of the temperature of cooling water after the start-up of the engine from an air flow meter 21, an intake-air temperature sensor 23, a heater-blower air-quantity setting switch 27 and the like. The control circuit 30 calculates a counter increment on the basis of these parameters and increases the value of a warm-up counter WCT by the calculated increment every predetermined period. The value of the warm-up counter thus increases corresponding to the actual rising speed of the temperature of cooling water.  When the value of the warm-up counter reaches a predetermined reference temperature, if the indicated value of the water temperature sensor falls below the reference temperature, the control circuit determines that an abnormality occurs in the water temperature sensor. The value of the warm-up counter which increases corresponding to the actual rise of the temperature of cooling water thus determines the timing of fault diagnosis, which allows accurate fault diagnosis.

Title: Heat pump air conditioner
Inventor: MATSUBARA MITSUNORI
IPC: F25B13/00
Filed: 1990-05-30
Abstract: PURPOSE:To prevent a rapid increasing in pressure of a pressure sensor while a three-way valve is being closed and a hating operation is carried out by a method wherein during a heating operation, a four-way valve is turned ON, a bypassing valve is turned OFF, and at the same time the four-way valve is turned OFF within a predetermined period of time when a heating operation is started and after compressor is energized and then the bypassing valve is turned ON. CONSTITUTION:In the event that a heating operation is erroneously carried out while closing a three-way valve B7 during an installing work, a four-way valve 2 is being turned OFF and a bypass valve 11 is turned ON and opened. Just after starting a heating operation is which a compressor 1 is operated, the operation becomes a cooling cycle and the bypass valve 11 is turned ON. Accordingly, refrigerant discharged from the compressor 1 passes through the four-way valve 2 and is changed to the refrigerant flowing to an outdoor heat exchanger 3 and to the refrigerant passing from the discharging pipe 12 through the bypass valve 11 in the bypass pipe 14 and a suction pipe 13. Pressure at a pressure sensor 10 is once decreased and the refrigerant also becomes from its liquid state to its gaseous state. After this operation, the four-way valve 2 is turned ON, the bypass valve 11 is turned OFF and the operation is changed over to a normal heating cycle. At this time, although the pressure at the pressure sensor 10 is rapidly changed from its low pressure to high pressure, an increasing in pressure is dampened due to the fact that all refrigerant are in gaseous state, and then no abnormal high pressure is not rapidly generated.

Title: Motor driving circuit of magnetic recording and reproducing device
Inventor: OKAMOTO CHIKAYUKI
IPC: G11B15/44
Filed: 1982-08-16
Abstract: PURPOSE:To reduce the sag of a tape due to the kick of an idler, by changing slowly the torque control voltage of a reel motor when the revolution of an oscillating idler reverses. CONSTITUTION:When the forward/backward revolving signal 14 of a motor 11 is inverted, an edge detector 17 delivers a pulse 20 having a certain degree of width. Receiving the signal 14, a driving circuit 18 sets the voltage 21 at a low level via a time constant circuit 19 and supplies the voltage to a motor driving circuit 12 to stop slowly the revolution of a motor 11. When the signal 20 is reset, the voltage 21 is raised up gradually with the time constant of the circuit 19. When the voltage 21 exceeds the threshold level, the motor 11 is controlled to increase slowly the torque of the motor. Thus the revolution of the motor 11 is reversed to suppress a reaction produced when an oscillating idler 3 is released from its press contact state. As a result, the tape sag is reduced.

Abstract: PURPOSE:To improve cornering performance of a motorcycle by letting the axis of a connecting shaft be on the plane which includes the grounding central points of both wheels and intersects the axle shafts of both wheels when a motorcycle advances rectilinearly. CONSTITUTION:A front frame 3 is capable of freely banking around a connecting shaft 7 with a main frame 6. The axis A of the connecting shaft 7 is on the plane which includes the grounding central point P1 of a front wheel 1 and the grounding central point P2 of a rear wheel 4 at the time of rectilinear movement, and intersects the axle shafts 8, 9 of both wheels 1, 4, and aligned with the central face X of a car body. Accordingly, at the time of cornering, a front frame 3 having the front wheel 1 permitting banking is inclined to the center of turning to be balanced with the centrifugal force. Thus, banking of the rear wheel can be restrained so as to be excellent in cornering performance. In case of a motorcycle in which the front frame is banked right and left, cornerings to the right and to the left are different only in direction, so that well-balanced cornering can be attained.

Title: Incoming control system for mobile body communication system
Inventor: SATO FUMIKAZU
IPC: H04W16/32
Filed: 1988-06-10
Abstract: PURPOSE:To efficiently perform incoming control on a mobile station by making access from a base station to which the mobile station is expected to move next to the mobile station when the mobile station passes through a base station at the end of exit in the area of each section station. CONSTITUTION:The probability of the movement of the mobile station extending over the section stations 30 is stored in an area station 32, etc., and a registration station A1B1 on which the mobile station 16 is registered as a section station table 138. The registration station A1B1 refers a section station code shown by the present location information of the mobile station 16 to the section station table 138, and derives the section station which manages an area where the mobile station 16 is expected to move. For example, since the mobile station 16 in traveling invades to the area of the section station A0B1C2 immediately after passing a road station (base station) A0B1C1D7 at the end, the registration station A1B1 retrieves the section station A0B1C2 in this case, and makes access from the road station to the mobile station 16. In such a way, it is possible to reduce the probability of invalid incoming connection to the mobile station, and to attain communication with a targeted mobile station appropriately.
